New sires emerge in June run

June’s proof run sees some familiar breeder names on the top 20 list of new genomic females – Emu Banks, Hindlee, Vala, Rockwella, Dillee and Numeralla.

Holstein Australia’s Rohan Butler says while this is not a surprise given their focus on genomics based breeding programs, what is interesting are the new faces emerging amongst the sire group.

“The likes of Jeronimo and Chairman remain as main stays with four of the breeders on the top list using these bulls, but using them alongside new sires such as Handle and Parachute with their first entries.

“This is a good and healthy thing. We should see young bulls. The best of the young sires from the best bulls and dams of the previous generation should progressively push out their older counterparts. It’s not surprising when a bull like Handle comes along.

“While he may not be a headline grabbing 400+ BPI, look a little closer and not only are his numbers very solid, he has a proof without many weaknesses. Breeders are then able to use him to create high ranking heifers with similar profiles, which is how the breed makes progress”. 

Topping the new genomic females list is Emu Banks Dewars 11606 (345 BPI) followed by Hindlee Jeronimo 20056 and Vala Parachute Rozie-ET, both on 332 BPI.

The top three on the young genomic females list (since 31 January 2018) remain the same – Vala Bandares Boliana-ET (400 BPI), Wilara Jeronimo Lollie-CNF-DPF-XIF-BLF-PO (397 BPI) and Illawambra Lawson Dallas 3914-CNF-DPF-BLF (393 BPI).

A change at the sharp end of the top cows list sees Gallrae 1051 Flamer Lola 1474-MFF-CNF-DPF-XIF-BLF (399 BPI) move up to third position, with Ivyhurst Wrangler Mystery 6194-OC (428 BPI) and Vala Bandares Boliana-ET still locking out the top two positions.
